Insanity: doing the same thing over and over again and expecting different results.

That's a stupid quote. The fact that it's often attributed to Ben Franklin is even more ridiculous. Insanity (psychological problems) rarely includes that as a symptom, and even when it does it's only a small part of the problem. (OCD doesn't count, because the compulsion doesn't include a belief that this time will be any different.)

Replace "insanity" with "stupidity" and the quote isn't quite as stupid.

Oh, it's not so bad a quote. If we define sanity around here as being more Bayesian (that's the waterline we're trying to raise, right?) then defining insanity as refusal to update when more data comes would make sense.
